Hi,
Harshey and Chase did a great experimentation which was basically a two step experiment to prove that DNA and not proteins are the actual carriers of genetic information from parents to offspring.
- In the first part of their experiment, they used bacteriophages (virus that eat bacteria). They used radioactively labeled sulphur(35S) medium to grow bacteriophages and observed that all the bacteriophages had proteins with radioactive sulphur(35S).
- In the next step they allowed these phages to infect bacteria and to their surprise, they found that the bacteria did not had radioactively labeled sulphur in them because the coat of bacteriophage stays outside the body of bacteria when it attacks it. This proved that DNA not proteins were the hereditary material.
- To make their results more reliable, they did a second experimentation in which, they marked the DNA of the phage with radioactive phosphorus 32P. After labeling DNA, they repeated the same experiment and this time, they found radioactive phosphorus inside the bacteria.
<em>This meant that the bacteria had DNA of phage entered inside them and this again proved that DNA not proteins are the hereditary material. You can see attached image for better understanding.

Hope it help!

1. The United States granted independence to Philippines in the year 1946, when the island liberated from the occupation of Japanese during the time of world war 11.
The independence was being established by the Treaty Mania. After Spanish-American war, the United States then acquired by Philippines in the time of 1898.
Before, Philippines it was colonized by Spain and then later by United States.
2. Unlike France, Russia and Britain the United States wanted to keep trade in China open.
3. When Philippines rebelled against United States rule, then the United States found itself using same tactics which were used by Spanish in Cuba.
Filipinos used Guerrilla warfare to undermine United States powers. It is through the military action which United States showed dominance over the Philippines.
